Create Simple and Clean password strength checker using jquery and css.

In CSS, jquery, by Steve

Jquery is very clean and easy to integrate in web applications. To create password strength checker with jquery is simple and can be done easily. Recently , in my latest project , I have used it and liked the way it changes color.

.

Here is the DEMO

Step 1: HTML Setup

Copy the following code inside your body tag or where ever you need this checker.

^?View Code HTML

<div id="single_form_element">
	<label class="label" for="new_pass">Password</label>
	<input type="password" name="password" value="" class="password-box"/>
	<div class="chk_avlblty chk_pswd"><span class="password-strength"></span> <span class="strength-text">Type Password</span></div>
</div>

.

Step 2: CSS Setup

Copy the following CSS code inside your stylesheet. You can change style as per your requirements.

#single_form_element{margin-top:50px;}
#single_form_element .chk_avlblty{margin: 10px 0 0 110px;width:110px;text-align:right;}
#single_form_element .strength-text{font-size:13px;font-weight:bold;}
#single_form_element .chk_avlblty span.password-strength{width:110px;-moz-border-radius:5px;-webkit-border-radius:5px;height:10px;background-color:#555;display:block;}
#single_form_element .chk_avlblty span.client-avail{display:block;}

         <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
	<script type="text/javascript" src="/demos/js/passwordstrength.js"></script>
		<script type="text/javascript">
		$(document).ready(function(){
			$( 'input.password-box' ).live( 'keyup', function() {
			var howStrong = passwordStrength( $( this ).val() );
			$( '.strength-text', $( this ).next() ).text( howStrong );
			var sColor = '#555';
			switch( howStrong ) {
				case 'Strong' :
					$( '.password-strength', $( this ).next() ).css( 'background-color', 'green' );
					break;
				case 'Medium' :
					$( '.password-strength', $( this ).next() ).css( 'background-color', 'lightgreen' );
					break;
				case 'Weak' :
					$( '.password-strength', $( this ).next() ).css( 'background-color', 'orange' );
					break;
				case 'Short' :
					$( '.password-strength', $( this ).next() ).css( 'background-color', 'red' );
					break;
				default :
					$( '.password-strength', $( this ).next() ).css( 'background-color', '#555' );
			}
			}).focusout( function() {

			});
 
	});

It looks like there’s no way to get a “Strong” password… any example?

the sticky notes tool is amazing. i was going to try and write something almost the same but this is way better. now only if i can ajax out the data to mysql that would rule. i want to have a user pick from a list or projects and get previous post projects and as they add/edit posts save to db. if anyone has some example functions for this – please send me a note, thanks

jQuery selectors are a combination of CSS 1-3, XPath, plus some custom code to glue it together. Essentially, the best parts from both of these query languages were taken, combined, and used to create the final jQuery expression language. If you already know CSS (which most web developers do) then you’re going to be fine.
